- To all whom it may concern:

Beit known that I, THEODOR KUNDTZ, a citizen of the United States of America, residing at Lakewood, in the county of Guyahoga 'and State of Ohio,.have inventedcertain new and useful Improvements in Blowers, Exhausters, and the Like; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1 it pertains to make and use the same.

tend upwardly This inventionrelates to improvements in blowers, exhausters and the like for mills and factories.

The primary object of this invention is to provide a blower, exhauster or the like rendered exceedingly powerful or eflicient and economical in operation by havingits fan-wheel operatively mounted on a lineshaft and inclosed by a casing or housing which is supported independently of the line-shaft so that of the housing comes upon the shaft.

Another object is to'accommodate the location of the fan-wheel and housing when the line-shaft is hung from and near the under side of a floor arranged between two adjacent stories of a mill or factory building by having the housing and fan-wheel exthrough and above-the said floor, and to support the housing from the said floor independently of the line-shaft.

Another object is to have the said housing composed of an upper section which is supported independently of the line-shaft and a lower section which is removably secured to the upper housing-section to facilitate the assemblage of the parts and so that the lower housing-sectio-ncan be separated from the upper housing-section to afford access to the fan-wheel or interior of the housing without disturbing the upper housingsection. v

Another object is not only'to accommodate the extension of the housmg and fan-wheel from within the lower into the upper of two adjacent stories of a mill or factory building but to have the upper housing-section supported from the floor within the upper story and to have the lower housing-section removably attached to the upper housingsection within the lower story and enable the removal of the lowerhousing-section within the lower story in which the line-shaft is located without interfering with the lineshaft, fan-wheel or upper housingsection.

the fan-wheel and housing;

no portion of the weight- Another object is to avoidthe necessity of using a separate engine or motor, or belting or gear ng, or separate power-transmitting means n the operation of the fan-wheel, and thereby effect a great saving in power; to avoid costly framework for supporting to prevent any bearing of any the line-shaft; to avoid the necessity, of using bear ngs on or in the housing, and to avoi lubrication of any portion of the housmg and fan-wheel.

Another object is to hauster or the like Wl'llCl'l requires substantially no care or rable in construction, readily installed,inexpenslvely maintained, economically operated, reliable and efficient in its operation and not liable to get out of order.

With these objects in of realizing any other advantages hereinafter appearing, this invention consists in certain features of construction, and combi nations andarrangeme'nt of parts, hereinafter described, pointed out in the claims, and illustrated in the accompanying drawings.

In the said drawings, Figure 1 is a top plan of a blower, bodying my invention, andalso shows the floor between two adjacent stories of a factory building. Fig. 2 is a verticalsection on line 22, Fig. 1, looking in the direction indicated by the arrow, except that the fan wheel is shown in elevation. Fig. 3 is a vertical section on line 3-3, Fig. 2, looking in the direction indicated by the arrow. Fig. 4 is a horizontal section on line H,

looking downwardly. Fig. 5 is a vertical section in'detail on line 5-5, Fig. 3, look portion of the housing upon provide a blower, ex-

exhauster or the like, cm?

attention, is simple and duview, and to the end ing inwardly. Fig. 6 is a vertical section in detail on wardly.

.Referring to the said drawings, A indicates a substantially horizontal floor arranged between two adjacent stories of a mill or factory building. Within the lower story and in suitable proximity to the under side of the floor A is a substantially horizontally arranged solid line-shaft B which has bearing in two boxes C and C' which are spaced longitudinally of the line-shaft and suitably supported from and rigid with the floor A. The line-shaft B is therefore hung from the floor A.

D indicates the fan-wheel of my improved line 6-6, Fig. 3, looking outblower, exhauster or the like. The said fan-wheel is operatively mounted on the line-shaft B centrally between the boxes C and C. Preferably the fan-wheel (see Fig. 2) isdivided, as at 7, centrally and longitudinally of its hub (Z into two. sections or halves, and oppositely arranged halves of i the hub d embrace opposite sides respectively of the line-shaft to which, the said halves -are clamped by suitably applied bolts E and nuts e, as shown in Figs. 2 and 4.

A casing or housing incloses the fanwheel and is divided substantially horizontall andpreferably substantially on a line wit the axis of the fan-wheel into two sections G and g which are arranged the one above the other and form the upper half and lower half respectively of the housing. 4

The fan-wheel shown is too large in diameter to render possible the location of the fan-wheel and housing wholly below the floor A or wholly within the story containing the line-shaft, and consequently the said floor is provided with'a hole a extending vertically therethrough and arranged to accommodate the extension upwardly through the floor of the housing and the fan-wheel within the housing. It will be observed therefore that the fan-wheel projects uphousing-section 'g, which is of' course ar-' ranged wholly below the saidfloor, is provided at its upper end and externally with laterally and outwardly projecting flanges 12 which are arranged next below the flanges 10 of, the upper housing-section and (see Fig. 2) are secured preferably removably by suitably applied bolts 13 and nuts 14 to the last-mentioned flanges.

By the construction hereinbefore it will be observed that the upper housingsection, and consequently the housing, are supported from the floor A independently of the line-shaft B,that is, independently of the line-shaft-supporting boxes C. The

, chamber 15 formed by and within the housing and containing the fan-wheel of course extends around the shaft and is only enough larger in dimensions than the fan-wheel to conveniently accommodate the location and operation of the fan-wheel." The housing is provided with two flues h and h arranged at opposite sides respectively and centrally of thehousing and extending exte'rnallyof described v the housing around the shaft B. The flues h communicate withand thereby form the 'inlets of the chamber 15 and through the inlets the dust or material to be sucked or drawn into the said chamber during the rotation of the fan-wheel is conducted into the chamber, and I indicatesfluesor ipes for conducting such dust or material om any desiredplace to the flues h. The flues h pref erably project laterally of the same side of the shaft B and diverge toward their outer ends. Each flue h is divided substantially horizontally centrally between the top and bottomof the flue and substantially on a line with the axis of the line-shaft, into two sections 17 and 18 arranged one above the other and formed on or rigid with the upper housing-section'G and lowerhousing-section g respectively. The upper section 17 of each flue h is provided at the bottom thereof and externally with laterally and outwardly projecting flanges 19,-and the lower section 18 of the said flue is provided at the top thereof and externally with laterally and outwardly projecting flanges 20 arranged next below the-said flanges 19 on the said upper flue-section and secured preferably removably by suitably applied bolts 21 and nuts 22 to the said last-mentioned flanges.

By the construction hereinbefore described it will be observed that the lower housingsection 9 and the connected flue-sections 18 are detached from the upper housing-section G upon withdrawing the nuts Hand 22 from the engaging bolts to permit the removal of the lower housing-section downwardly from the upper housing-section to afford access to the fan-wheel and interior of the housing. 1 I

To accommodate the projection of the fines hlaterally of the line-shaft as hereinbefore described the line-shaft extends throughholes 23 formed in the said flues,

and the relative arrangement of the upper sections and lower sections of the flues his preferably such relative to the line-shaft that the hole It in each flue h is formed partia-lly in the upper section and partially in the lower section of the flue.

I The housin is provided at the bottom with a latera y projecting flue K which communicates with and forms the outlet of the chamber 15, through which outlet any dust or other matter sucked or drawn into the said chamber during the rotation of the fan-wheel is discharged from the chamber, and L represents a flue or pipe for conduct ing the discharge from the said outlet to any desired place. 7

By the provision of a blower, exhauster or the like in accordance with my invention no separate engine or motor, or belting a pulleys or gearing, or the like, are required to rotate the fan-wheel, and no lubrication of or other care or attention to the fan-wheel cient in its-operation and the said floor,

housing is required. Such a blower, exhauster or the like is not only simple and durable in construction and economically operated, but readily installed, inexpensively maintained, reliable and eflinot liable to get out of order. Of no inconsiderable value is the great saving in power resulting from the mounting of the housed fan-wheel directly upon the line-shaft without any interference with the line-shaft by the housing.

What I claimiis:- v 1'. The combination, with a floor arranged between two stories of a building, and a suitably supported shaft arranged below of a fan-wheel operatively mounted onthe shaft, and a casing or housing inclosingthe fan-wheel'andhaving its fanwheel -containing 'chamber provided with an inlet and an outlet, said housing comprising. an upper section and a lower section, the upper housing-section extending above and below the floor and supported from the floor above the floor, and the lower ousing-section-being removably secured to the upper housing-section.

2. The combination, with a suitably sup ported shaft, -of a fan-wheel operatively mounted on the shaft, and a casing or hous- 1n inclosin the fan-wheel and supported independent y of the shaft and provided with a flue arranged centrally of the housing and extending around the shaft, which flue communicates with the chamber-formed in and by the housing and projects from and,

at an' angle to the shaft and is divided substantially into two on a line with the axis of the'shaft oppositely arranged sections which are .removably secured together, said flue having a hole arranged to accommodate the location and operation of the shaft, the aforesaid chamber having an outlet, the housing being divided substantially on a line with the axis of the shaft into two sec tions which carry opposite sections respectively ofthe aforesaid fluc.

3. The combination, with a suitably supported'shaft, of a fan-wheel 'operatively mounted on the shaft, ing inelosing the fan-wheel and provided with a flue arranged centrally of the housing and extending around the shaft, which flue communicates with the chamber formed in and by the housing and projectslaterally of the shaft and is divided substantially horizontally and substantially on a line with the axis of the shaft into two sections which are removably secured together, said flue having a hole arranged to accommodate the location and operation of the shaft, and said housing being divided substantially horizontally and substantially on a line with the axis of theshaft into an'upper section and a lower section, the upper housing-section beinosupported independently of the shaft andcarrying the upper section of the aforesaid flue and provided with a flue which communicates with and forms the outlet of the aforesaid chamber.

In testimony whereof, I sign the foregoand a casing or housing specification, in the presence'of two wit- IIGSSGS.
